ProText 1985 - DesText 1995.
This video took five attempts before anything usable was recorded. The first copy of DesText kept resetting the PLUS and the second copy was only a little better, even so the APP locks the PLUS (at 3:42) when I take the printer option. Ho Hum.
I'll keep looking and might find a better copy eventually.

That's nice and interesting. Really reminds me of the ST's GEM desktop.
Interoperability in Arnor tools is very, very impressive.
Remember, there was no "standard" back then to share data between applications!
